Answer all questions. Write full sentences for all explain and evaluate questions. Time guidance: 90 minutes.

Explain briefly two ways in which sustained deflation can raise the real burden of debt for households and firms in the UK.

(Total for Question 1 is 4 marks)

Write an essay assessing whether deflation or inflation poses the larger overall threat to economic stability and growth in a modern UK-style open economy. Consider short-run and long-run effects, winners and losers, policy responses, and any conditions under which one is more damaging than the other. You should include analysis, consider diagrams where relevant (describe any diagram you would draw), and reach a supported judgement.

Evaluate the view that deflation is a greater threat to a modern UK-style economy than inflation.

(Total for Question 2 is 25 marks)

Define the term 'disinflation' in the context of UK consumer prices.

(Total for Question 3 is 2 marks)

Explain how a sustained rise in aggregate demand can lead to demand-pull inflation in an economy that is close to full capacity.

(Total for Question 4 is 4 marks)

Explain briefly how cost-push inflation occurs, giving one concrete example of a cost increase that can trigger it in the UK.

(Total for Question 5 is 4 marks)

Explain the basic idea of the quantity theory of money as a monetary cause of inflation, in the context of a UK economy.

(Total for Question 6 is 4 marks)

State two groups that tend to gain from unexpected inflation, and give a one-sentence reason for each (UK context).

(Total for Question 7 is 2 marks)

Question 1

M1 deflation raises the real value of nominal debts because the money used to repay obligations gains purchasing power
A1 example: fixed mortgage payments stay the same in nominal terms while incomes and prices fall, so payments become harder to meet in real terms
M1 second mechanism: deflation can reduce incomes and profits, lowering borrowers' cash flows and increasing default risk
A1 link: falling revenues for firms make servicing existing nominal debt more difficult, amplifying solvency problems during deflation
Answer: Deflation increases the real value of nominal debts, making fixed repayments heavier in real terms; and it reduces incomes and profits, cutting borrowers' ability to service debt and raising default risk.

Question 2

Level 1 (1-5): Basic statements about inflation and deflation showing limited understanding. Rare or no use of examples. Judgement, if any, is weak and unsupported.
Level 2 (6-10): Some correct analysis of the effects of inflation and deflation, with a few relevant examples or mechanisms. Limited evaluation, and a weak or partially balanced judgement. May describe a diagram but not fully use it.
Level 3 (11-15): Clear analysis of both inflation and deflation, including short-run and long-run consequences, distributional effects and likely policy responses. A balanced evaluation with a supported judgement and reference to diagrams where appropriate.
Level 4 (16-20): Thorough analysis and evaluation across multiple dimensions: macro stability, growth, financial sector risks, and distributional consequences. Diagrams are correctly described and used to support argument. Judgement is well supported and considers conditions and caveats.
Level 5 (21-25): Excellent, well-structured evaluation that integrates theory, empirical plausibility and policy realism. Presents nuanced arguments about when inflation or deflation is worse, considers magnitude and persistence, identifies winners and losers, and reaches a convincing, qualified conclusion. Diagrams and alternative perspectives are used effectively.
Indicative content:
- Explain costs of inflation: menu costs, shoe-leather costs, uncertainty, distortion of price signals, tax/BRacket creep, redistribution from savers to borrowers, loss of international price competitiveness if domestic inflation exceeds trading partners'.
- Explain costs of deflation: postponed consumption/investment, rising real debt burdens, falling nominal wages and profits, increased default risk, potential liquidity trap limiting monetary policy effectiveness.
- Distinguish expected versus unexpected inflation: predictable low inflation allows indexation and planning, unexpected inflation causes arbitrary redistribution and uncertainty.
- Consider magnitude and persistence: low, stable inflation may be benign or desirable; high or hyperinflation is clearly damaging. Mild deflation might occur with quality improvements, but prolonged deflation is harmful.
- Discuss who gains and loses under each scenario: borrowers vs savers, fixed-wage workers, firms with pricing power, exporters and importers.
- Policy responses: monetary policy to fight inflation (raise rates) but rate hikes have trade-offs for growth; for deflation, central banks may cut rates, use quantitative easing or fiscal expansion, but effectiveness is limited when rates are near zero.
- Diagram description: supply and demand or AD/AS diagram to show demand-pull inflation (AD shift right) and cost-push inflation (SRAS shift left) and how deflation might follow AD falling (AD shift left). Use diagram to discuss output vs price trade-offs.
- Consider open-economy aspects: exchange rate effects, imported inflation, competitiveness and the role of external shocks.
- Evaluate relative severity by context: in a modern economy with flexible policy tools, persistent deflation may be harder to escape; however, very high inflation can destroy financial intermediation and collapse savings, so relative threat depends on scale and persistence.
- Conclude with a qualified judgement, e.g. that persistent deflation is a greater threat to growth and financial stability in a low-rate environment, while uncontrolled high inflation is catastrophic for living standards and institutions; the correct policy priority depends on starting conditions, central bank credibility and fiscal capacity.

Question 3

B1 a fall in the rate of inflation, i.e. prices are still rising but at a slower rate than before
B1 not to be confused with deflation, which is a fall in the general price level
Answer: A fall in the rate of inflation: prices continue to rise but at a slower rate than previously; not the same as deflation.

Question 4

M1 identify that AD increases (C, I, G or X-M rising)
M1 explain that with little spare capacity firms increase output only a little and begin to bid for scarce resources
A1 show that rising demand for inputs pushes up costs, or firms raise prices because of stronger demand
A1 conclude that the general price level rises, producing demand-pull inflation
Answer: When AD rises near full capacity, firms cannot expand output much and instead compete for scarce inputs, pushing up costs and prices; stronger demand also lets firms raise prices, so the general price level increases.

Question 5

M1 cost-push inflation arises when firms face higher costs and pass them onto consumers via higher prices
M1 state mechanism: higher input costs reduce short-run aggregate supply, shifting SRAS leftwards, raising price level and lowering output
A1 give example: a large increase in oil prices or a sharp rise in minimum wage or imported intermediate goods becoming more expensive
A1 link example to likely outcome: higher transport/production costs raise prices across many sectors, causing inflation
Answer: Cost-push inflation happens when firms' costs rise and they increase prices. For example, a big rise in global oil prices raises transport and energy costs across the economy, shifting SRAS left and raising the general price level.

Question 6

M1 state the core relation that if the money supply grows faster than real output, too much money chases the same goods
M1 mention the typical equation MV = PY in words: money supply times velocity equals price level times real output
A1 explain implication: if M rises rapidly while V and Y are stable, P must rise, i.e. inflation
A1 short evaluative note: velocity may change and central bank control of M is not perfect, limiting the theory's predictive power
Answer: The quantity theory says rapid growth in the money supply relative to real output causes inflation because more money chases the same quantity of goods (MV = PY); if M rises much faster than Y then P must rise. In practice velocity changes and central banks influence money, limiting the theory's simple application.

Question 7

B1 borrowers: unexpected inflation reduces the real value of fixed nominal debt, easing the real burden
B1 some firms with pricing power: can raise nominal prices faster than rising costs and so may see higher nominal profits in the short run
Answer: Borrowers, because unexpected inflation reduces the real value of fixed nominal debts; and firms with pricing power, because they can raise prices faster than costs and increase nominal profits temporarily.
